Abstract : This report addresses the development and application of experimental methods for characterizing the soil behavior during the shock loading and subsequent unloading accompanying cratering detonations. The program was initiated to understand the behavior of the multiphase effective stress pore-air material model when used to predict the velocities of high speed ejecta (crater material which is ejected with sufficient velocity to become entrained into the rising fireball/dust cloud or form long-range ballistic ejecta fragments). The experiments were fielded on events DISTANT IMAGE and MINOR UNCLE, conducted on native soil at the White Sands Missile Range, and events HUSKY JAGUAR 1 and 2, conducted on a test bed backfilled with Socorro plaster sand. A small scale simulation of the HUSKY JAGUAR 2 experiment was conducted in the DNA halfspace facility.
